We need a new PCode request commands and reply codes
to be added as a prepartion patch for QGV points
restricting for new SAGV support.
v2: - Extracted those changes into separate patch
(Ville Syrjälä)
v3: - Moved new PCode masks to another place from
PCode commands(Ville)
v4: - Moved new PCode masks to correspondent PCode
command, with identation(Ville)
- Changed naming to ICL_ instead of GEN11_
to fit more nicely into existing definition
style.
